Summary
The moon has been added to the World Monuments Fund’s (WMF) list of threatened heritage sites for the first time due to risks from commercial and governmental lunar activities.
The WMF highlights concerns about looting and damage to artefacts from Apollo missions, such as Neil Armstrong’s footprints and objects left on the moon.
WMF calls for international protocols to protect lunar heritage as private space tourism and missions increase.
The 2024 list also includes sites in conflict zones and areas endangered by climate change or unsustainable tourism.
No, I am totally not. You are hung up on the part where you think that for something resembling smoke to exist, an atmosphere is necessary. Have you never seen RCS thruster being fired in zero gravity?
Yes, there won’t be fields of funnels causing smoke clouds that block the view from Earth. But exhaust products being expelled into the vacuum causing measurable dimming effects? Certainly at some point.
I don’t get what you’re missing here. An atmosphere is the trapping of gasses, the moon doesn’t have enough gravity, they will disperse into space very quickly. It’s why the ISS doesn’t have it’s own atmosphere and if they pumped out smoke from that thing it would drift into space, not from a smog cloud around them.
If you have shown anything on this thread is that you are unfamiliar with all the topics you’ve brushed past.
…. A particle ejected VS Smog… don’t you notice how engines don’t produce smoke in space…? That’s the comparison you should be making.
Using an RCS on earth would look the exact same, other than particles would stick around instead of as you can plainly see in the video, its bursts are IMMEDIATELY gone.
You’re comparing an apple to a piece of steel now, they’re totally different situations and particles.
Engines in space don’t produce visible smoke because A) they are precision engineered to burn 100% of the fuel they are supplied with, and what is colloquially known as smoke is unburned particles. All this awesome smoke that engulfs rockets before they take off? Most of it is vapour from water under the platform, protecting the structure from melting. B) Thrusters in general are build to expel the reaction mass as fast as possible in order to go as fast as possible with the least amount of fuel.
So yeah, you are trying to compare what happens in a cars’ engine with what’s going on in the exhaust: It’s the same stuff but under very different circumstances.
